[Thermal Printer Apparatus 10 in the Possible State of Printing]

When the second module 100 is closed, as shown in FIGS. 1A and 1B, the second module 100 has a recessed space 25 between the gear box portions 23 and 24 of the first module 20. ), Both ends of the lock shaft 160 are locked to the locking grooves 23b and 24b, respectively, and are engaged at four points A, B, C, and D, and are integrated with the first module 20.

In the thermal printer apparatus 10, the second module 100 is accommodated in a recessed space between the gear box portions 23 and 24 of the first module 20 so as to have a rectangular shape, and the gear box portions 23 and 24 are formed. It does not protrude above, and the height is H, as shown in Fig. 1B, and is a low height.

In particular, as shown in an enlarged view in FIG. 1C, the thermal head portion 122 is pressed against the platen roller 50 by the spring force of the head pressurizing spring member 130, and the printing portion 200 is formed. Moreover, the rotating blade 140 approaches and opposes the blade part 61 of the fixed blade 60 from the Z1 side, and furthermore, the gear 147 meshes with the gear 73, and the cutter apparatus 210 is formed. Further, a straight paper passage portion 220 obliquely downward in the Y1 direction is formed between the ceramic plate 121 and the paper guide surface portion 22a.

In the formed cutter device 210, the rotary blade 140 is positioned at an initial rotational movement position, and there is a gap 211 between the rotary blade 140 and the fixed blade 60 as much as paper passes. have.

In this state, it becomes the thermal printer apparatus 10 of a printable state.

[action]

With the second module 100 closed, a paper automatic feeder (not shown) operates, and a thicker thermal paper is sent out as shown by arrow J in FIG. The tip is inserted into the paper passage portion 220 so as to be sandwiched between the platen roller 50 and the thermal head 120, and the platen roller 50 and the thermal head 120 sandwich the thick thermal paper. It is inserted into and opposes.

By the print command, the thermal head portion 122 is driven to generate heat, and the motor 40 is driven to rotate the platen roller 50 through the gear train 80, and the platen roller 50 and the thermal head ( 120 is sandwiched between the thick thermal paper, the thick thermal paper is transferred while printing on the thick thermal paper, and the printed paper portion passes through the cutter device 210 through the gap 211 to exit (221). It is sent out from The heat generated in the thermal head portion 122 is radiated through the second frame 101, which also serves as a heat sink. When the printing is finished, the motor 30 is driven by the cutting command to rotate the rotary blade 140 through the gear train 70 and the gear 147, and the blade 141 is a blade of the fixed blade 60. While rotating 61 in the Z2 direction, the rotary blade 140 rotates about 90 DEG so that the printed paper portion is cut. After that, the motor 30 continues to drive, and the rotary blade 140 rotates once to return to the initial position.

In addition, cutting of the thick thermal paper starts from the one end side of the width direction. Therefore, by stopping the rotation of the rotary blade 140 just before the cutting reaches the final position, and by rotating the rotary blade 140 reversely, the thick thermal paper is left uncut at one end in the width direction. Paper cutting is made.

Here, since the rotary blade 140 having a higher rigidity than that of the plate-shaped blade is used, the cutter apparatus 210 has a sufficiently long service life even if the thermal paper is thicker than the usual thickness of more than 150 µm.

In addition, since the paper passage portion 220 is straight, the thick thermal paper is smoothly conveyed inside the thermal printer apparatus 10 without being subjected to strong resistance.

In addition, for thin thermal paper, as shown by the arrow K in FIG. 1B, it is inserted from the bottom side paper insertion opening 26 and is guided to the point of the platen roller 50 through the paper passage part 28. As shown in FIG. , It is curved at the point of the platen roller 50, and after that, it is cut and cut like the case of the thick thermal paper mentioned above.

Further, for maintenance, the lock release lever 150 is moved in the Y2 direction to release the locks at the C and D points, and the Y1 side of the second module 100 is pulled up to open the thermal printer device 10. , The gear 147 is separated from the gear 73, the rotary blade 140 is returned to the initial position by the initializing spring (145).

In this state, since the gear 147 is separated from the gear 73 and the rotation transmission path which reaches the rotation blade 140 from the rotation blade driving motor 30 is interrupted, the thermal printer apparatus 10 is mistakenly made. Even when the rotating blade drive motor 30 is driven by turning on the power of the power source), the rotating blade 140 does not rotate, and the risk that the operator injuries a finger due to the malfunction of the rotating blade 140 Is prevented.

Moreover, when the thermal printer apparatus 10 is opened, the fixed blade 60 and the rotating blade 140 can be covered with a protective cover member, so that an operator can not hurt a finger. This will be described later.

Claims (12)

A first module and a second module, The first module includes a rotating blade drive motor, a platen roller driving motor, a platen roller rotated by the platen roller driving motor, and the rotating blade driving motor on a first module frame. It is a configuration including a rotating blade consisting of a main body rotated by a plate-shaped blade fixed to the main body, The said 2nd module is a structure containing a printing head and a fixed blade in the 2nd module frame, The printer apparatus according to the embodiment, wherein the printing head and the platen roller face each other, and the fixed blade and the rotating blade face each other while the first module and the second module are coupled to each other. According to claim 1, wherein the first module and the second module in a coupled state, between the first module and the second module, a straight paper passage portion is formed, And a printing head and the platen roller, which face each other, and the fixed blade and the rotating blade which face each other, are arranged side by side at a downstream point of the paper passage portion. The shape of claim 1 or 2, wherein the first module frame includes a main body portion at the center and a gear box portion protruding from the main body portion at both sides thereof, and the main body portion is recessed from the gear box portions at both sides. And the second module is accommodated in the recessed portion. The printer apparatus according to claim 3, wherein the second module is supported at a position inside the gear box portions on both sides so as to be rotatable. The printer apparatus according to claim 1 or 2, wherein the second module is completely detachable with respect to the first module. The printer device according to claim 1 or 2, wherein an initializing spring for returning to the initial position is provided on the rotating blade. The protective cover member located in the retracted position when the first module and the second module are coupled to each other, when the coupling between the first module and the second module is released. And a protective cover mechanism for moving to a cover position covering both or one side of said fixed blade and said rotating blade. The printer apparatus according to claim 7, wherein the protective cover mechanism is configured to move the protective cover member from the retracted position to the lid position by using a spring force of a spring. The printer apparatus according to claim 8, wherein the spring is a leaf spring piece which protrudes from the protective cover member and is integrally formed with the protective cover member. The printer device according to claim 1 or 2, wherein the rotating blade is configured to fix a plate-shaped blade to a main body which is a molded part. The printer device according to claim 1 or 2, wherein an end of a plate-shaped heat sink on the upper surface of the printing head is used as a blade of the fixed blade instead of the fixed blade. The printer device according to claim 1 or 2, wherein an end of the ceramic plate on which the printing head is formed is a blade portion of the fixed blade instead of the fixed blade.
